I did some searching on flexural U joints and found the following:

http://www.engin.umich.edu/labs/csdl/papers/DesignOfLargeDisplacementComplia
ntJoints.pdf
http://www-cdr.stanford.edu/~motohat/publications/NRO_finalreport.pdf
They may be a source of ideas for folks that want to experiment with
flexural joints for certain telescope parts and functions.
However, I still don't know what Don's flexural U joint looks like in his
collimation cell....
