    Abstract: A junction connection is provided that is used to connect a torque transmitting junction component (2) to a hollow shaft (1). The junction component (2) includes a continuous recess which has a shape which corresponds to the outer cross-section of the hollow shaft (1) and which is used to receive the hollow shaft (1). The hollow shaft (1) includes a press stopper (8) in the connection area between the hollow shaft (1) and the junction component (2). The press stopper (8) forms, at least sectionally, a press fit with the wall of the hollow shaft (1). The junction connection enables the transmission of comparatively high torque during the entire service life thereof. The junction connection is also compatible with thin-walled, light-weight hollow shafts. The junction connection limits production costs, mounting and maintenance.
