What is the name of the component marked on the diagram?
Generally, a wheel (disk)-shaped component with high machining precision is installed at the tail end of the shaft on the non-driving side of the turbine. Its main function is to transmit the necessary dynamic information to probes such as speed sensors, phase sensors, and shaft displacement sensors, through pre-machined flat surfaces, grooves, or toothed structures.
Speed measurement tooth, mainly used in conjunction with a speed measurement probe. Provides the engine speed.
This seems to be at one end of the coupling; it’s probably used for turning the shaft
