"FYI - It is not easy to do and I have yet tp find the "Magical" Screw Driver required to take the screw out of the shaft."
I tried various size hex wrenches (which didn't fit) and then tried a torx which did fit. Had to use a pair of channel lock pliers to apply enough torque to loosen but it did come out.
