  A quasitoric manifold $M$ is a $2n$-dimensional manifold which admits an
action of an $n$-dimensional torus which has some nice properties. We determine
the isomorphism type of a maximal compact connected Lie-subgroup $G$ of
$\text{Homeo}(M)$ which contains the torus. Moreover, we show that this group
is unique up to conjugation.
