Looks to me like you can just slip it on and tighten down the Allen screw. And get pulley bore adapters if needed.

There is only one screw to secure it.

My thought if I tightened it would be off center and not rotate properly.

Yes, but only if the shaft actually allows for it.
Usually they are hardened steel and for the sprocket is a cut out section - not big enough for the grub screw to hold on.
But you got me thinking....
Assuming the diameters match than it should be possible to use an angle grinder or a really good file to make a small notch for the grub screw....

According to the picture you showed of the motor and shaft, there is a cut out section for the set screw.
