ABSTRACT OF THE DISCLOSURE In the case of drive units, more particularly for ships, comprising a hollow driving pinion located axially between a hydraulic coupling and a con- trollable bypass coupling for selectively bypassing the hydraulic coupling, stresses may arise, for example as a result of misalignment, but also as a re- sult of changes in the foundations arising during operation. Such stresses are difficult to avoid because appropriate bearing locations are required to support individual components of the drive, for example the actual transmission, but also the drive shaft between the hydraulic coupling and the power plant. According to the invention, these stresses may be eliminated simultaneously, in all types of transmission, by arranging, between the power plant and a support bearing in front of the hydraulic coupling, a universal coupling designed to permit radial, axial and angular misalignment between the drive shaft and the power plant drive shaft.
