Flexible coupling accomplishes the purpose of any coupling, but the main advantage over rigid coupling is flexible coupling is to accommodate the unavoidable misalignment between shafts in some machinery.
The flexible coupling also allows a degree of axial movement between the coupling shafts as possible due to thermal expansion.
As compared with a flexible coupling, the rigid coupling has limited application because rigid couplings do not have the ability to compensate for shaft misalignment, therefore, used where shafts are already positioned in precise lateral and angular alignment.
