Local engineering shop has done a very good job on the adaptor.
The original fitting (bottom left) is soft alloy, they recreated it in steel, with a big bolt , and counterbored to make a location for the hub prong. There's a transverse hole to take a spring pin (though I might use a bolt instead) to transmit the torque, and the nut at the end is held on with a split pin.
The hub had a tapered hole down the centre and a UNC or UNF thread at the end, they cut the thread off, bored the hole out and fitted a length of steel tube in there with a flat on the prong so it only slides into the adaptor one way.
