Shaft Coupler to Shaft attachment

I recently bought a new prop, shaft, and coupling. Our old shaft and coupling were drilled right through, with a bolt right through the entire thing to prevent any kind of slip.

The new coupler simply has 4 bolts, which tighten the grip of the coupler on the shaft. There is no keyway, no setscrews, nothing other than pressure holding the coupler to the shaft.

I don't have any experience in this stuff, so I just wanted to ask if this is a normal arrangement? Is the force of friction alone considered strong enough to hold a shaft to a coupler?
