ABSTRACT:
The present invention relates to a coupling (1) for a ship propulsion system to be arranged between a first shaft section (3) and a second shaft section (5) of a propeller shaft, comprising a first radial surface (17) facing a second radial surface (19), said first and second radial surfaces (17, 19) are transversal to the axial extension of the first and second shaft section (3, 5), wherein said first and second radial surfaces (17, 19) are connectable into an axially engaged condition and disconnectable into an axially disengaged condition, wherein said first and second radial surfaces (17, 19) are rotationally secured relative to each other in said axially engaged condition by means of at least one shear-carrying element (27) seated in opposite recesses (23, 25) arranged in the first radial surface (17) and the second radial surface (19), respectively, taking up shear forces directed substantially parallel to said first and second radial surfaces (17, 19), each of said opposite recesses (23, 25) comprises an open end facing the other one, wherein said at least one shear-carrying element (27) in said axially engaged condition abuts an axial abutment surface provided in the vicinity of each of said recesses (23, 25) for provision of a distance (29) between the first radial surface (17) and the second radial surface (19).
