1. A lockout device for a gearbox, comprising:
a housing;
a shaft comprising a first plurality of teeth at a first end, the first plurality of teeth being configured to engage a second plurality of teeth on a drive train within the gearbox and transmit rotation from the shaft to the drive train;
an inner collar configured to sit around the shaft, the inner collar further configured to sit at least partially between the shaft and the housing, the inner collar comprising a plurality of threadless holes; and
an outer collar configured to sit around the shaft and at least partially between the inner collar and the housing, the outer collar comprising a plurality of threaded holes configured to receive a plurality of bolts passing through the plurality of threadless holes, wherein rotation of the plurality of bolts can adjust a relative position of the inner collar and the outer collar, wherein as the inner collar and the outer collar are pulled closer together the inner collar is pushed against the shaft and restricts a displacement of the shaft with respect to the housing.
