A clamp for use in testing machines to prestress a joint between a driving shaft and a driven shaft, both of which are externally threaded with each having a flat surface abutting the other in a plane substantially perpendicular to the driving axis. The clamp is internally threaded to cooperate with the external threads and has bolts which, when tightened, produce a force on the abutting surfaces to compressively preload the joint from forces on the flanks of the external threads. |
