This image shows a computer-generated 3D model of a rigid shaft coupling. The coupling consists of a white, cylindrical main body with various diameters and a red anodized end. A lateral clamping screw (set screw) is visible on the red section, which serves to fix a shaft. Such components are used to connect two shafts in a torsionally rigid and precise manner when no misalignment between them needs to be compensated.
