Claim 20:
21. A method for imparting rotational torque upon a substantially cylindrical object, comprising:
coupling an assembly having a substantially circular surface, with a diameter approximately equal to that of the substantially cylindrical object, to a substantially cylindrical object;
the assembly comprising a plurality of fingers extending from the substantially circular surface, positioned about a circumference of said substantially circular surface, each finger of the plurality of fingers having at least one surface that is substantially tangential to the circumference of the substantially circular surface;
wherein each finger of the plurality of fingers includes a biased spline having a first end pivotally retained in a chamber in a tip of each finger, biased so that a second end of each spline is urged away from the finger in which it is retained;
securing each spline to a surface of the substantially cylindrical object; and
rotating the assembly about the center of the substantially circular surface, thereby rotating the plurality of fingers about that center; and
thereby imparting a rotational torque upon the substantially cylindrical object via the interface between each spline and the surface of the substantially cylindrical object.
