Not really, with the full round input shaft when you assemble the flexible coupling to it, you will find that in order for you to install and tighten the pinch bolt, it has to pass through a notch that is machined into the input shaft.
You may have just one or two (or at most three) possible serrations that you can slip your flexible coupling flange onto. After that, you will find that the pinch bolt won't pass through the notch.
