What would be a suitable flexible coupling type for a 10 hp Diesel engine to a 6kva alternator at 3000 rpm , both having 25 mm keyed shafts ?

MAnufacturers' coupling calculators usually add a hefty "Application service factor" when an engine is the driving unit/prime mover.
1.25 for an electric motor
2.0 IC engine 3 cyl or fewer
The design of the keyway/keyseat may be important for good fatigue life.

For a generator? No way. The engine needa direct control of speed. For low horsepower? This can't be expensive. The Dodge Paraflex couplings work well here. Falk Grid Couplings work well but are expensive and require a lot of maintenance.
Never coupled to internal combustion engines, but have experience with fluid couplings on conveyor drives. Fluid coupling mfrs indicate good results in coupling to IC engines.
