My Z axis coupling is 8mm by 8mm ?!?

The Z axis coupling I received is 8mmX8mm not 8mmX5mm. When it fits onto the stepper motor shaft the coupling has a wobble because it cannot be centered on the shaft with only two set screws 90° opposed. I can make my own spacer or amazon a new one if these won't work well. I haven't got the unit fully assembled but I Don't want to get too far if a wobbly shaft will cause issues down the road.

Also as you can see my fingers are very dirty. Whatever is used to paint the components black needs some reevaluating. I already washed my hands before the picture too. It was everywhere

Well Amazon.com had the correct components.
