The present invention relates to a torque transmitting cardan shaft (2), and, in principle, includes within the shaft an adapted intermediate member or shaft (10), which has a first end section (11), that is intended for a rotationally rigid co-action with a first universal joint yoke (21) and a second end section (12), opposite said first end section (11), intended for a rotationally rigid co-action with a second universal joint yoke (22). The intermediate member or shaft (10) and its end section (11) is configured as and comprises two parts or sub-sections (2a, 10), which are mutually joined via a safety coupling arrangement (7), by means of which a free coupling of said subsections (2a, 10) from one other can be ensured immediately after the torque, between said subsections, exceeds a predetermined value, determined by the construction of the safety coupling arrangement (7). A first end section (2a) and its universal joint yoke (21) includes an axially orientated cylindrical groove or recess (13), which has a centre axis (13') that is co-ordinated with or aligned with a rotational axis (11') of said first end subsection (11) and its co-ordinated universal joint yoke (21). The circular groove or recess (13) is dimensioned to enable enclosure of a major cylindrical part (17) of said safety coupling arrangement (7) and its safety unit part (17) and co-operate with a disc (18). The first end section or extension (2a) and its yoke (21) are integrated formed to one single piece.
