The coupling system (1) comprises of two individual units (2,3), each of them permanently joined to the shaft with a hub (4,5). The two units are connected by a central area (6), which engages with the notched areas (7,8) of the two units. Several seals (11-14) are positioned between the central part (6) and the units. An inner sealing element (17,18) is guided axially along a coaxial cylindrically shaped surface on the central part (6), while an outer sealing element (19,20) is joined to each of the individual units.
