A partition (124, 125) is provided between the shaft-hub seat (114, 118) and the other force transmission region(s) so that the clamping zone created under load in the shaft-hub seat is not affected by the other force transmission region(s). The coupling (100) is used to join together modules in a modular tool holder arm and comprises a male part (112) which closes a first module and is provided with a central journal (114), and a female part (120) which closes a second module and has a central cavity (118) for receiving the journal. Fitting the male and female parts together creates a shaft-hub seat forming a first force transmission region. At least one further clamping zone is created under load in the other force transmission region(s). Independent claims are also included for (a) a tool insert support piece for a tool holder arm for a machine tool, the support piece being provided with one of the above coupling parts for inserting into a mounting piece, (b) an extension or intermediate piece for a tool holder arm for a machine tool, provided with at least one of the above coupling parts on one side, (c) a main mounting piece for a tool holder arm for a machine tool with one of the above coupling parts for receiving the support, extension or intermediate piece, (d) a tool holder arm comprising the support piece, the main mounting piece and optionally the extension or intermediate piece and (e) a machine tool with one of the above coupling parts for connecting to the support, extension, intermediate or main mounting piece, or to a the tool holder arm. |
