Claim 0:
1. An apparatus for imparting rotational torque upon a substantially cylindrical object, comprising:
a coupling assembly having a substantially circular surface having a diameter approximately equal to that of the substantially cylindrical object wherein the coupling is adapted to receive the substantially cylindrical object; and
a plurality of fingers extending from the substantially circular surface wherein a proximate end of each finger is attached to the coupling and a distal end extends away from the coupling;
wherein each finger includes a spline at least partially recessed within a chamber therein, wherein a first end of the spline is pivotally retained in the distal end of each finger, and a second end of the spline adjacent the coupling is biased so that the second end is urged outward from the finger that retains spline; and
wherein each spline is adapted to grip a surface of the substantially cylindrical object, when the substantially cylindrical object is received between the fingers so that rotation of the coupling causes rotation of the substantially cylindrical object.
