OEM Coupler Does the Job - For Now

I'm an engineer, so whoever designed this for KitchenAid made a poor material choice decision unless their goal was planned obsolescence. Having said that, it was easy to replace the worn coupler (it screws onto a threaded shaft) and we're hoping it'll last 1 - 3 years with infrequent blender use. Much better on several fronts rather than buying a replacement blender.
