Blue and green shafts rotate around a fixed axis.
Blue springs and red pins maintain contact between yellow sprags and the two shafts.
The arrows show which link is the driving at different times.
When the blue shaft is driving, its two way rotation can be transmitted to the green shaft only in clockwise direction.
When the green shaft is driving, its two way rotation can be transmitted to the blue shaft only in anticlockwise direction.
