I didn't see any details on their web site, but if they use a hydraulic
coupling then that should isolate the prop during a strike assuming proper
design of the hydraulic drive. There is likely though some loss of
efficiency as I don't know of any hydraulic drives that are 100%
efficient.
I read that a clutch protects the engine from prop strikes, and a harmonic
dampener isolates torsional harmonics. I take that to mean an isolation
rubber dampener, as is common in industrial motors and transmissions.
