Some main propulsion medium speed engine installations operate with a hydraulic oil type fluid coupling between the engine and the reduction gearbox instead of a mechanical clutch. With this type of installation a separate flexible coupling is not normally fitted. Why is a separate flexible coupling usually omitted from this type of installation?

There is insufficient room to fit a flexible coupling between the engine and gearbox when a fluid coupling is fitted.

There are no engine torque variations in the drive when a fluid coupling is used so a flexible coupling is not required.

The hydraulic fluid in the coupling isolates the gearbox from the engine vibrations.

There is natural slippage between the drive and driven parts of the fluid coupling and a flexible coupling would prevent this slippage.
