Leviton Single Pole Switch with Pilot Light Model 277W Box

i assume both switches are single pole? How to wire depends on what wires you have in the box (i.e. the circuit they are in).

change the switch

The Cooper combo device requires neutral wire to energize the outlet.
To control outlet with switch, the Hot side of device must have break-away fin.
Remove break-away fin.
Connect jumper wire from switch load side to outlet Hot side.

Wired as shown in illustration, the pilot light and the Load will come on each time switch is turned on.
The illustration show Load is light bulb.
In your case, the Load will be an outlet instead of light bulb.
So the Load will have 2 wires. The black wire from switch connects to brass screw on outlet. The neutral connects to silver screw.
Bare ground wires connect to green screws.

I made following diagram based on Cooper pilot light instruction sheet:
Neutral wires are usually the white wires that are twisted together in back of box and covered with wire nut.
If your box does not have neutrals, you can also connect bare ground wire to silver screw until you have time to run neutral wire to box >> ground to anything but ground screw is not code and not recommended.

Unless I misunderstand you, you just need to get a single switch, and a duplex outlet with a matching plate. Your hardest part will be to decide the color of the devices and plate (rectangular, double-D holes, etc. I'd suggest, that for "preserving domestic tranquility" you hire you mate (if any) as consultant on these matters.
(Wire it as it is now; that is if the switch controls the outlet the wiring should still be easy to follow.
DO turn off the power first!)

I have 120Volt cooper 277 pilot light switch here in my office.
Dang instruction sheet shows wiring for all kinds of cooper devices.
EXCEPT pilot light switch.

So I tested with multimeter and came up with following:
Key to any wiring device is color of screws.
Hot from breaker box always goes to dark-colored screws.
Neutral always goes to silver-colored screws.
Brass screws are for Hot wires from breaker or Hot going to Load
Green screw - ground

It's the same as you wire any single pole switch.

This is a single pole light switch and should be wired as any other SP switch. The only difference is that is has a pilot light. All the white neutral wires are tied together and then pushed back in the box with none connected to the switch. The grounds are tied together with a jumper wire connected to the green screw on the switch. That will leave you with 2 or more black wires. If you have just two normally you can connect them to the two screws on the switch and it does not matter which screws. However it may be that with the pilot light you need to connect the wire going to the light to the top screw and the power wire to the bottom or vice versa. Try both ways. If you have more than 2 black wires you need to connect the incoming power black wire and outgoing power black wires together and then jump to one of the screws on the switch. The black wire left over is the black wire going to the light itself. If none of this works then it is obvious the pilot light in the switch is burnt out.
