A clamp (50) for use in testing machines to prestress a joint between a driving shaft (30) and a driven shaft (20), both of which carry portions (22, 32) which are externally threaded with each shaft having a flat surface (36, 38) abutting the other in a plane substantially perpendicular to the driving axis (16). The clamp (50) is internally threaded (52) to cooperate with the external threads (22, 32) and has bolts (54) which, when tightened, produce a force on the abutting surfaces (36, 38) to compressively preload the joint from forces on the flanks of the external threads (22, 32). |
