No worries I have figured this out. So the center screw is what fastens a pipe that runs through the centre of the stand. This pipe is what is used to adjust the various heights of the arms. The clamps are what actually pin to this pipe. I ended up having to drill out the bolt on top, once I drilled it out that"s when I saw what actually failed. Over torqued from the factory along with lock tight and when I loosened the bolt originally the fitting that is pressed into the pipe has a threaded center which broke loose and was just spinning. Drilling it out was the only option. Now off to work to make the repairs and fabricate my own mic/iPad adapter. Thanks for the input.
