The handle stem should be threaded, and the handle should twist off that. I just just a piece of aluminium flat bar, and tapped it to thread onto the shaft. I then put a nut on the top to secure it.
If I was doing it a again, I would use a chunk of aluminum round stock, maybe 5/8" as it would look nicer.
