You get couplings that take up misalignment, like Oldham couplings.
Trouble with those is, they do not "fasten" the "motor-end" of the screw. I
simply machined hollow hubs with "interference-fit" bores for screw-end and
motor-shaft, oh, but NOT "set-screws", but CLAMP type fit. Required a bit
more care in machining, but result is the screw is axial with the motor and is
rigid, depending on motor's bearings for thrust AND radial bearing.
