Technical Question - Engines

Hi CCIP how did the u boats drive 2 propellors with one engine? I understand they were two separate single shafts, one per engine, and that they did not have the ability to connect the shafts, although I think british submarines did have this facility. Did they have a sepatate dynamo and motor per shaft? In any event this would probably be an emergency system as one diesel driving two shafts and props would be less efficient than driving a single shaft surely?
