Paragraph Number

79

In one embodiment, the driver 320 includes a threaded distal end 322, a shaft 324, and a thumb-screw 326. The threaded distal end 322, shaft 324, and thumb-screw 326 can be used to connect the driver 320 to the coupling 110/third coupling 220. The thumb-screw 326 is connected to the shaft 324 such that rotation of the thumb-screw 326 about the longitudinal axis of the shaft 324 turns the threaded distal end 322 to engage or disengage with the coupling 110/third coupling 220. The thumb-screw 326 can be rotated by an operator.
