    (b) the a flexible drive tension transmitting component having a first drive end and a second drive end, the first drive end is attached to the first helicoid and the second drive end is attached to the second helicoid; and

    whereby a first tension force transmitted through the flexible drive tension transmitting component causes a first drive portion of the flexible drive tension transmitting component adjacent the first drive end to unwind from the first helicoid and forces the shaft to rotate in the drive direction and, sequentially, a second tension force transmitted through the flexible drive tension transmitting component causes a second drive portion of the flexible drive tension transmitting component adjacent the second drive end to unwind from the second helicoid and forces the shaft to rotate in the drive direction.
