Right. The crankshaft (->Kurbelwelle) of the Diesel engine and the electric motor shaft can be coupled to the propeller shaft (-> Propellerwelle) as part of the drive shaft (-> Antriebswelle). So maybe you are looking for a term that refers to the shaft coupling (-> Wellenkupplung).

Stern and bow buoyancy tanks.
The aft and forward parts of outer shell are constructed as stern and bow buoyancy tanks and are used to dampen longitudinal pitching of the boat. Both tanks have flood slits and one vent valve each.

That's a tough one. I have never heard of those tanks and I have hurt my brain trying to figure out how they work (inertia of moving masses? I just don't get it).
