Incorrect Topic/article
The object constructed in this article is commonly called a "mapping torus", which already has a wikipedia article. A "torus bundle" is a fiber bundle with fiber homeomorphic to a torus.
Orientation-preserving?
Why are you restricting to orientation-preserving maps? Juan Marquez

Hmm, the article at the moment states that any torus homeomorphism is either finite order, a power of a Dehn twist, or Anosov and talks about the trace of the homeomorphism. First of all, I suppose it would be neater if instead it discussed the mapping classes, but is the trichotomy even correct? I don't see why a trace −2 homeomorphism should be the power of a Dehn twist. --pred (talk) 21:51, 6 April 2012 (UTC)
False statement
The article defines "torus bundle" as a bundle (whose fibre is a torus) over the circle as base space.
But it is not true that the base space of a torus bundle must be the circle. It can be any topological space at all.2600:1700:E1C0:F340:781C:B988:BE1F:5107 (talk) 21:37, 19 December 2018 (UTC)
