Adapter for FP gearbox

This year my team is investigating into using the FP w/ the gearbox(black).

However, we are confused as to how we are supposed to attach to the output “shaft” on this thing.

I’m not positive, but I thought a couple of years back teams were given an adapter.

Is there any place that we could buy an adapter or any suggestions?
