A Flexible Coupler 5mm to 8mm coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. 8mm and 10mm cupler are used for cnc machine and 3d printers.

Flexible coupler

Featured snippet from the web

flexible coupling exists to transmit power (torque) from one shaft to another; to compensate for minor amounts of misalignment; and, in certain cases, to provide protective functions such as vibration dampening or acting as a “fuse” in the case of torque overloads.
The purpose of a flexible coupling is to transmit torque from one piece of rotating equipment to another, while accepting at the same time a small amount of misalignment. Flexible coupling misalignment is expressed, as an order of magnitude, in thousandths of an inch.
