      Rather than take on the shaft, it is far easier to cut the coupling with a grinder.
      Just use a 3" disk and make multiple light passes down it's lenght until the groove is just about to the shaft.
      Then use a hammer with a large screw driver/steel chisel to crack open the final bit of coupler..
      Will leave your shaft unharmed.
      If it still will not let go (some are a real pia), rotate the coupling 180 degrees and do it again.
      Had one of the flange ears shatter using the socket trick one time.
      This technique got the flange off real quick and is a lot cheaper than a shaft.
      Best to bring the grinder with you "just in case" if you own one.
      Couplers are not that expensive.

      Thanks, guys. I think I will try to slip a socket in between the transmission and coupling first. If that doesn't work then I will look around for something we can cut the shaft with, as Pete suggested.

      I've never cut a 1" stainless shaft before, but I did spend a week threading all of the silicon bronze bolts for a 30-ton schooner, and that was not much fun.
