how do you remove the coupling drive on a Kitchen Aid KSB50B Blender?

The plastic coupling drive on my 5 speed Kitchen Aid Ultra power melted. I can buy a replacement part # AP2930430. is it a screw or pressed on the motor shaft?

look at the little space between the blender and the black coupler... the round shaft really has 2 flat edges. When I ordered my coupler, it come with the tool to grab the flat edges. The coupler then gets un threaded CLOCKWISE.
