Flexible Coupler (5mm to 6 mm) flip-flop LDR sensor module is usedIntroduction : Connect motor shaft to anything else with a set screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co linear and will help reduce bending effects. The way they are cut, create a spring effect in the X Y & Z linear axis but not in the rotational axis. That means that you will not get increased backlash so
