... What is needed to
get the square slot?

Another approach is to not use the keyway on the existing
shaft. You could:

Cross drill for a taper pin, or

Machine the shaft and handle for a 'dutchman' which
is a round key. The idea is you assemble the shaft
to the hub, and drill the face of the assembly,
centered at the parting line between the two. A
tight fitting round pin is then driven into the
hole.

If you've ever taken apart a southbend crossfeed handle,
you'll know what this technique looks like.
