I'm not sure I understand.  Is the pictured shaft the input or output shaft?  Is the basic idea to just put a stiff 
spring between the input and output shaft so that one is always pushed forward and the other always pushed to the 
rear...eliminating the possibility of the input shaft building inertia?
