Yes is the answer, it can be used to correct some misalignment and can absorb some shocks and cushion.

Which one is a flexible coupling? Explain, please.

Agree with you, Thanks @Ganeshr.

The Correct answer is yes.

Bush pin type flange coupling is used to connect of shafts which having a small parallel misalignment, angular.

Misalignment or axial misalignment. This is a modification of the protected type flange coupling which has pins.

(covered by rubber or leather bushes) and it works with coupling bolts. Generally, it is used to assemble electric Motors and machines.

No, flexible coupling can have some misalignment of shaft, and that is what makes them call flexible coupling, so answer is Yes.

Bushed pin flexible couplings are commonly used for directly connecting electric motor to a machine.

The couplings permits axial movement and care of shock or slight alignment.
