The 20-year-old was most recently with fellow League One outfit Inverness Caledonian Thistle, but he was made redundant last month after the Highland club entered administration.
His arrival at Palmerston comes in the wake of last weekend’s injury crisis where all three forward starters against Alloa suffered hamstring injuries.
QOS boss Peter Murphy said: “We are delighted to have been able to secure Adam’s signature and add him to the squad.
“It was unfortunate what happed to him and Inverness, but with injuries to our current front players it has the potential to work out really well for both parties.
“He has also played as an attacking midfielder, so, again, it gives the squad options.
“We look forward to working with him and welcome him on board for the rest of the season.”
