Abstract
A coupling (10; 100; 200; 400) for use between the modules of a modular tool holder arm, in particular a machine tool, with a male coupling part (12; 112; 212; 412), forming the end of a first module and containing a central, axially symmetrical journal (14; 114; 214; 414), and a female coupling part (20; 120; 220; 320; 420), forming the end of a second module connected to the first module and containing a central, axially symmetrical seat (18; 118; 218; 318; 418). In the engaged state, the two coupling parts form a shaft-hub seat (14, 18; 114, 118; 214, 218; 414, 418) as a first transmission location and at least one other transmission location. At least under load, a first stress field (26) develops in the first transmission location, and another stress field (27, 28) develops in the at least one other transmission location, wherein separation (24, 25; 124, 125; 224; 324; 424) of the first transmission location from the at least one other transmission location is provided, so that the respective stress field (26, 27, 28) is formed without being impacted by the respective other transmission location(s).
