This is wrong case of a double Cardan joint: the pin axles on the yellow-violet intermediate shaft are perpendicular each other.
Although due to the gear planetary drive of two gear sectors and orange crank, angle between input (or output) shaft and the yellow intermediate shaft is always equal to A/2 (A is angle between input and output shafts),
the joint loses the feature of velocity constant when the input and output shafts are not in a straight line (A differs from 0 deg.).
So pay special attention to assembling the intermadiate shaft.
