Aircraft; Human Factors
On climbout when the gear lever was selected up we received the following EICAS messages: NOSE DOOR OPEN warning; GEAR DISAGREE warning; NOSE WHEEL STEERING INOP caution; WOW INPUT caution.  We informed tower of the situation and we were handed off to Departure.  We continued the climb to 8;000 maintaining 200 knots and requested radar vectors.  We informed ATC that we would be returning for landing after we completed the QRH procedures.  We also informed the Flight Attendant/passengers; Dispatch and local company Operations of the situation.  After completing procedures/checklists we returned for landing.  After landing and decelerating the aircraft started to shudder quite significantly under 80 knots until stopped.  We stopped straight ahead on runway and had the CFR do an inspection.  I asked them to check the torque links and they reported that they were not connected.  I suspect that after we pushed back from the gate the torque links were reconnected enough for us to taxi to the runway with steering but were not fully locked in and when the nose gear strut extended on takeoff it pulled them apart.
CRJ-200 Captain reported returning to departure airport after multiple nose gear related error messages. Ground Personnel reported the nose gear steering torque links were not connected.
