A mechanical component called a grid spring coupling is used in engineering and technology to transfer rotational motion and torque between two shafts while compensating for small misalignments. It is made up of a number of flexible springs or metal grids organized like a lattice. A Grid Spring Coupling's main function is to join two shafts, some of which may not be exactly aligned, and smoothly transmit power from one to the other without resulting in excessive wear or damage. The grid springs' flexibility allows for angular, axial, and radial shaft misalignment.
