Someone else suggested a link that explains exactly how to unthread the old coupling... and it works. It took me about 90 seconds to fix my blender. But in case that link is dead, here's a summary:

(1) Note that the coupling (the round part with teeth) is threaded to the blender motor in reverse to a standard threading. So it screws off just like a bottle top, but in a clockwise direction.

(2) place the blender base on a tabletop, facing you. You should probably unplug it.

(3) take a punch or a flathead screwdriver, and place it against one of the coupling teeth that is furtherest away from you.

(4) strike the back of the screwdriver with a small hammer or maillot. The result will spin coupling clockwise. It may take several tries, but the coupling will eventually spin clockwise faster than the motor, and it will begin to unthread.

(5) unscrew the old coupling, and screw the new coupling into place (counterclockwise). Note that the new coupling will tighten itself every time you use your blender, so no need to worry about tightening it too much.

(6) Make a smoothie to celebrate your success!
