hex shaft coupler
hex shaft coupler
(OP)
I need to connect a 5/16 hex shaft to a 1/2 shaft machined to this cross section: http://w ww.robotco mbat.com/i mages/stor e_dustinsh aft_lg.jpg
Any suggestion what my options are without custom fabrication? Thanks.

What's the application? Pushing, pulling, rotating? What load, what RPM, what environment? More data will yield more useful responses.

Regular tape or glue probably wont work. I thought of making a coupler by filling up a steel tube (with square cross section) with epoxy and inserting the shafts into the epoxy but I am not sure if this will be strong enough.
The web site http://www.staffordmfg.com unfortunately only lists hex shaft collars, not couplers.

Can you use a standard round shaft coupling then put in a roll pin?

Improvements will probably suggest themselves.
Drill a 23/64 hole in the 1/2" shaft, push in the hex shaft and fill with araldite again......or silver solder....or roll pin.

Can you thread the shafts and just go to a machine shop and ask for a custom coupler nut with the 5/16 thread and 1/2 thread in this coupler.

Look at the OEM section for sprockets. They have square bore and hex bore sprockets. Hopefully you are aware of chain couplings and the rest of this concept is fairly academic.
