What's the difference between rigid coupling and elastic coupling?

Rigid coupling is simple in structure and low in price, which is suitable for the case of good concentricity of two shafts. The elastic coupling has a complicated structure and high price, which is suitable for the situation that the concentricity of two shafts is not very good, and it is suitable for the situation with torsional vibration (vibration reduction).
