description A device for handling well pipe includes a mandrel including an upper end, a lower end and a long axis extending between through the upper end and the lower end. The mandrel secures to a top drive of a drilling rig. A threaded collar is located on an outer surface of the mandrel to loosely engage threads of a well pipe. An annular force generating assembly is carried on the mandrel and positioned between the upper end and the threaded collar. The force generating assembly applies a load to an upper end of the well pipe along the long axis, enabling torque to be transmitted between the threaded collar and the well pipe. The force generating assembly may be cams or a hydraulic piston.
