I had this problem when I was doing my Master six years ago, I came up with my research title and concept note I submitted it to my supervisor and it looked likehe was not interested in the area of research I chose so he suggested another topic, though I was not happy with the topic I wanted to earn my MSc so I agreed, but frankly it was very difficult to put ideas together, then I gave up and request for a new supervisor who we went had similar interest so I finished my Msc! Problem is not only to students but to their supervisors ( actually I hate this term, I prefer them called ADVISORS) as well! However, as others have suggested the best way is for students themselves to come up with their well research topic for Msc thesis/dessitation write up!
