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). |
