There were only a few pterosaur similarities to bat flight. The big ones
flew a bit more like albatrosses, but had a completely different
mechanism for applying loads to the skeletal spar and for alleviation of
gust loading

You might with equal validity think of the lift and thrust producing
flight mechanisms of any one of the three as being something of a hybrid
of the other two. However, I don't recommend that sort of an analogy
because of the specific differences in flight control mechanisms between
the three and because of the gross differences in the way power was
applied to the wing during flapping flight.
