Collet adapters work because a hole in the adapter shaft (machined to fit your motor or gearbox shaft with precision) is split along it's length several times is forced to contract (usually by the prop drive plate) tightly against the prop shaft. Collet type adapters usually provide a more true center than any other type of adapter meaning less vibration.
