collision with TimeSig

[Stefan Thomas]

Dear lilypond-users,
I have a collision between the note and the text of the TimeSig in the below quoted example.
Is there any possibility to avoid this?
Thanks for help,
Stefan

noten = { c''1 }
tempotakt = { s 1 ^\markup { \column { \upright "subito piu mosso"   \line { "(" \note # "4" #0.75 "= 120)" } \upright "molto rit." } } }
\layout{

  \context {                    
    \type "Engraver_group"
  
    \consists "Text_spanner_engraver"
    \consists "Text_engraver"
    \consists "Dynamic_engraver"
    \consists "Axis_group_engraver"
    \name "TimeSig"
  }
  \context {
    \Score \accepts TimeSig}
        }
   
     \new Score
{ <<
   
    \new TimeSig  { \override Score.TimeSignature #'style = #'( )
    \tempotakt  }
    \new Staff { \noten     }
>>
}
