Ok, if I understand you correctly: the coupler is welded to the motor shaft? I'm guessing it's more likely you have a keyway and setscrews. Sorry to be so picky, but my setup is using a hub as well, but without any welds, just setscrews, and I don't think it will stand the test of time. Since your system has given you a proven 62 kilometers, I'd like to emulate it as best I can...
